elemental-0.78-p1.tgz

Features

  • Revamped experimental C and F90 interfaces

  • Added entrywise and (unoptimized) singular-value soft-thresholding
  • Added (unoptimized) Robust PCA example

Bug fixes

  • Fixed mistake in Grid( MPI_Comm comm ) constructor which would have greatly effected performance
  • Fixed typo in CMakeLists.txt which prevented specification of MPI_Allreduce+memcpy based MPI_Reduce_scatter

Maintenance

  • Renamed LockedView() member function in Matrix and DistMatrix classes to Locked() to avoid confusion with LockedView function
